The Invisible Trillion · What You Can Do That Actually Matters

Shelf Three: Things That Matter a Lot

The interesting leverage, for most people, isn’t in personal consumption. It’s in collective action and in what you make of yourself. The question is which versions of each actually work.

Vote, when you’re old enough — and not just for president. The decisions that shape whether the costs of technology grow or shrink, whether AI gets built carefully or recklessly, whether data centers land in water-stressed places or not, are made by people you can vote for or who are appointed by people you can vote for. The gap between a government that takes these questions seriously and one that doesn’t is enormous, and you move it, a little, by voting.

Presidential races get the attention and often matter least for the specific issues in this book. Local races are where data center siting, water rights, zoning, and utility decisions get made. A county commissioner seat can decide whether a facility goes in the aquifer-draining spot or the closed-loop-cooled one. Most people skip those elections. You shouldn’t.

And there’s a kind of election most adults don’t know they can vote in. Public utility commission races — in the states that elect commissioners rather than appoint them — decide who allocates the rate increases from Chapter 5 between data centers and the households living next to them. Eleven states elect their commissioners. Turnout is often under 20%, which means a small organized group can move the result. If you live in one of those states, that may be the most important vote you cast on anything in this book, and almost no one else is watching it.

Support the people who do the work you can’t. Investigative journalism and public-interest legal groups are the actors that actually produce change in this space, and both run on money. When you have income, even a little, a subscription to one outlet that does real reporting, or a donation to one rigorous advocacy or legal organization, is worth more than any personal-consumption change you could make. Pick carefully — some are rigorous, some are vibes — and I’ll name specific ones a little later in the chapter.

Become genuinely good at something real. This is the most important thing on the page, and it’s the hardest to feel at fourteen because the payoff is years away. Let me say it as plainly as I can.

The people who actually change how any of this works — who design a more efficient chip, who figure out how to cool a data center without draining an aquifer, who write a regulation that holds up, who report the story that shifts opinion, who price the risk everyone else is ignoring — are people who can do something. They earned a skill. They spent years getting good at a specific thing, and now the world pays them for it.

That last part matters more than it sounds. The goal isn’t just expertise. It’s expertise you can make an honest living from — a craft the world will actually pay for, that produces something you can point to and check.

Here’s why I keep coming back to that. The surest protection against becoming a person you wouldn’t respect is being able to feed yourself with real work. People who can do something valuable don’t have to live off a cause, a brand, or a hustle. People who can’t, sometimes do, and that’s where the drift starts.

You can watch it happen: someone goes into an “issues” career sincere, learns that the visible part — the posting, the speaking, the being-known-for-caring — pays better and costs less than the actual work, and ten years on they’re a personality with opinions and no craft. The cause became the career, and the career became the grift. What keeps the other kind of person honest is that they have a real skill to fall back on, and would rather use it than perform.

So pick something real. It almost doesn’t matter which, because a world running on technology needs an enormous range of competence, and very little of it is the stuff that gets talked about.

Whichever of you likes building physical things: there’s the whole world of hardware — the chips themselves, the power electronics, the cooling systems, the grid equipment, the batteries. The people who make these things better have direct leverage over nearly every number in this book, and they’re paid well, because the skill is rare and the work is real.

Whichever of you prefers the physical world to the screen: there are the trades. Electricians, HVAC technicians, the people who actually build and run the infrastructure this entire book is about. They’re in short supply, and harder to offshore or automate than people like to claim. Someone who can wire a building or service a chiller has more practical leverage over how the physical world works than a hundred people with opinions about it.

Whichever of you likes numbers: there’s a quiet, consequential world of people who understand the money — the capital structure behind the buildout, how utility rate increases get split between data centers and the people nearby, how retirement savings got concentrated into a handful of companies, how to tell a real bet from a bubble. Most of the public argument about the economics is made by people who can’t actually do the math. If you can, you have leverage almost no one else has — the work is just being right about numbers other people would rather not check.

Whichever of you likes science: materials, battery chemistry, the measurement work that tells us whether the industry is doing what it says. Whichever of you likes computing: the architecture work from Chapter 13 — efficient models, edge inference, open-source tools, and the security of all of it. Whichever of you likes finding things out and writing them down: the craft of actual reporting, which is a different thing from the brand of commentary. And whichever of you likes teaching: every one of the people above had to learn from someone.

And whichever of you is drawn to law. There’s real, unglamorous legal work here that almost no one does — the cases tedious, the clients under-resourced, the lawyers across the table among the best paid in the country. It’s also the work that produces actual outcomes: the Southern Environmental Law Center beat xAI in Memphis because someone read the Clean Air Act’s “major source” language carefully and applied it to a strategy built to evade it. Environmental, utility, administrative, and municipal law are where most of this lives.

The same drift applies here as anywhere — the track that reins in bad behavior also rewards being known for fighting it, and the political-adjacent corners, the attorney-general path most of all, are as much a launching pad for ambition as a public-interest job. If it calls to you, it’s a real path; hold it loosely, and watch what the work does to the people a decade ahead of you on it.

The common thread is not the field. It’s the shape: get genuinely good at one real thing, good enough that the world will pay you for it, and you’ll have both leverage and the freedom to keep your integrity — because you never had to sell it to eat.

One more, and it’s the flip side. Some jobs, and some projects inside good companies, are making the world worse. You’ll have to decide, eventually, whether to work on them. The easy move is not to think about it and take the paycheck. The right move, usually, is to think about it and sometimes walk away. A lot of competent people quietly declining to work on bad things is one of the few forces that actually reins in corporate behavior — and having a real skill is what makes walking away possible, because you have somewhere else to go.
